Bontrager Interchange ANT+ Combo Sensor

Bontrager's Interchange ANT+ Combo sensor is a speed/cadence sensor in one. It includes a 5mm crank cadence band magnet, aero wheel magnet and a silicone mounting strap to fit most chainstays. It wirelessly transmits your data to a variety of ANT+ enabled receiving devices including Bontrager Node computers (sold separately). Installation is a snap, too.

I like this device. I connect mine directly to an iPhone 5. So far I have no problems connecting to Map My Ride or Wahoo Fitness apps. Everything works as expected.
Installation was easy, just needed to unscrew a pedal for the cadence sensor. You can install the base unit with included zip ties or pictured plastic strap (which works very well).

It took 10 minutes to install only because you have to remove and re-install a pedal. The pairing was automatic and reconnects easily. If the wheel magnet or the crank magnet passes the sensor it connects within a few seconds.

Speed/Cadence sensor does not work with iBike iPro Generation III. The item is advertised as compatible with Ant+ head units, but obviously does not work with everything. Check with http://www.thisisant.com for compatibility with your particular Garmin unit, etc.
